When Nintendo of America opened Club Nintendo in Canada & the US, the White Nintendo DS Game Case was one of the original items available in the rewards catalog, but for 600 coins.
There was also a Siver coloured one that came with an Aluminium stylus, for 700 coins. I started saving up for that... but then they removed it and the White from the catalog.
It was just gone one day. In part do to the fact that there were three DS game case and Stylus Sets that were also available for 600 coins.
I didn't really care for them, a friend has one and I've seen one in person and my option hasn't changed.
To me, they feel cheap, the spine and covers of a hardcover book with two foam inserts, one holding a rainbow stylus set.
Because they could hold three more games
and came with the extra styluses
* more people ordered them.
The White Nintendo DS Game Case just came back on the catalog one day earlier this year.
*Styluses is the proper plural form for Stylus, however, Styli is also the proper plural form for Stylus.
It's been this way for the past eight/nine years when an American English Dictionary first listed
both Styluses
and Styli as the plural form for Stylus.
